The model needs to make the following corrections to the 3D object: 
1. Change the shape of the object to resemble a corner brace plate connector. This typically has an L-shaped or angular structure, which is different from the current long, flat piece with rounded ends.
2. Add another hole to the object. Currently, there is only one hole visible at one of the semi-circular ends. The object should have two holes.
3. Ensure that the holes are positioned near the center of the semi-circular ends. Currently, only one hole is visible and it is located near the center of one of the semi-circular ends. The same positioning should be applied to the other end.
